Description

Technical Field

[0001] This application relates to the field of seal processing, and in particular to a seal molding production line. Background Technology

[0002] Seals are components or materials used to prevent fluid or solid particles from leaking between adjacent mating surfaces and to prevent external impurities (such as dust or moisture) from entering the interior of machinery and equipment. The production of seals usually requires workers to cut rubber raw materials on a reel into rubber blocks of a specified length and embed multiple rubber blocks into multiple cavities on a mold. The mold uses heat and pressure to vulcanize the rubber blocks into seals. Due to overflow or flow, the rubber blocks in adjacent cavities stick together to form rubber pads. Workers need to use a punching die to precisely cut along the contour of the seal to separate the seal and the rubber pad, thus achieving mass production of seals.

[0003] Workers need to place the multiple rubber blocks cut by the cutting machine into the multiple cavities of the mold one by one, which increases the workload of the workers and extends the production cycle of the seals, thereby increasing the production cost of the seals. Summary of the Invention

[0004] To address the issue of production costs for seals, this application provides a seal molding production line.

[0005] This application provides a sealing component compression molding production line, which adopts the following technical solution: A sealing component molding production line includes a base, a feeding assembly, a cutting assembly, an mounting device, a molding assembly, and a unloading assembly. The base surface is provided with feeding stations, cutting stations, mounting stations, molding stations, and unloading stations spaced apart. The feeding assembly is connected to the surface of the base facing the feeding stations and is used to mount and guide rubber raw materials on a reel towards the cutting stations. The cutting assembly is connected to the surface of the base facing the cutting stations and is capable of cutting the rubber raw materials at the cutting stations into rubber blocks of a specified length. The molding assembly is connected to the surface of the base facing the molding stations and is capable of heating and pressurizing multiple rubber blocks to vulcanize and mold them into rubber pads with multiple sealing components. The mounting device is connected to the surface of the base facing the mounting stations and is capable of clamping the rubber blocks at the cutting stations and placing them at the processing end of the molding assembly. The unloading assembly is connected to the surface of the base facing the unloading stations and is capable of clamping the rubber pads on the molding assembly towards the unloading stations.

[0006] By adopting the above technical solution, the reel is installed on the feeding assembly. The feeding assembly guides the rubber raw material on the reel to the cutting station. The cutting assembly cuts the rubber raw material at the cutting station into rubber blocks of a specified length. The mounting device clamps the rubber blocks at the cutting station and places them on the processing end of the molding assembly. The molding assembly heats and vulcanizes multiple rubber blocks to form rubber gaskets with multiple seals. The unloading assembly is located near the molding station. The unloading assembly clamps the rubber gaskets on the molding assembly and moves them to the unloading station. This achieves automated processing of the sealing component molding, eliminating the need for manual cutting of the rubber raw material into rubber blocks and placing them sequentially on the molding assembly. This reduces the workload of the workers, shortens the processing cycle of the sealing components, and thus reduces the processing cost of the sealing components.

[0007] Optionally, the feeding assembly includes a guide roller, an mounting roller, a clamping roller, at least two synchronous pulleys, and a synchronous belt used in conjunction with the synchronous pulleys. The mounting roller is rotatably connected to the machine base surface and is coaxially fitted onto the reel. At least two synchronous pulleys are rotatably connected to the machine base surface at intervals. The synchronous belt tensions and connects the two synchronous pulleys, and the axes of the synchronous pulleys and the mounting roller are parallel to each other. The clamping roller is rotatably connected to the machine base surface, and the axes of the clamping roller and the synchronous pulleys are parallel to each other. A clamping gap is left between the clamping roller surface and the synchronous belt for the rubber material to pass through. The clamping roller surface and the synchronous belt surface clamp both sides of the rubber material and drive the rubber material closer to the cutting station. The guide roller is rotatably connected to the machine base surface, and the axes of the guide roller and the mounting roller are perpendicular to each other. The guide roller surface allows the rubber material to roll into contact with and embed into the clamping gap.

[0008] By adopting the above technical solution, the reel is coaxially sleeved on the outer circumference of the mounting roller. The end of the rubber material on the reel passes through the guide roller. The roller surface of the guide roller makes rolling contact with the rubber material and is embedded in the clamping gap. The roller surface of the clamping roller and the surface of the synchronous belt correspond one-to-one to clamp the two sides of the rubber material and drive the rubber material closer to the cutting station, thereby achieving stable transportation of the rubber material.

[0009] Optionally, the feeding assembly further includes an adjusting rod and at least two limiting strips. The adjusting rod is connected to the surface of the machine base facing the timing belt. The adjusting rod is located between the guide roller and the pressure roller. The axis of the adjusting rod is parallel to the axis of the timing wheel. One end of each of the at least two limiting strips is slidably connected to the surface of the adjusting rod, and the other end of each of the at least two limiting strips abuts against the surface of the timing belt. The sliding direction of the limiting strips is parallel to the axis of the adjusting rod, and a limiting gap is left between the at least two limiting strips for embedding the rubber material. The at least two limiting strips abut against both sides of the rubber material in the width direction to form a positioning.

[0010] By adopting the above technical solution, the adjusting rod is located between the guide roller and the pressing roller. The rubber material on the guide roller guide reel is provided with a limiting gap. The surfaces of the two limiting strips correspond one-to-one with the two sides of the rubber material in the width direction to form a limit, so that the rubber material is not easy to deviate on the surface of the synchronous belt, thereby ensuring the accuracy of the cutting component in cutting the rubber material.

[0011] Optionally, the cutting assembly includes a cutting seat, a cutting cylinder, a cutting tool, and at least two positioning plates. The at least two positioning plates are spaced apart and connected to the surface of the machine base. A positioning gap is left between the positioning plates and the surface of the machine base for the rubber material to pass through. The surfaces of the positioning plates and the surface of the machine base correspond one-to-one to clamp the two sides of the rubber material in the thickness direction to form a positioning. The cutting seat is slidably connected to the surface of the machine base. The sliding direction of the cutting seat is parallel to the axis of the guide roller. The cutting cylinder is connected to the surface of the cutting seat facing the positioning plate. The axis of the piston rod of the cutting cylinder is parallel to the height direction of the machine base. The cutting tool is connected to the end face of the piston rod of the cutting cylinder. The surface of the positioning plate is provided with a plurality of slots spaced apart for the cutting end of the cutting tool to be embedded. The slots communicate with the positioning gap, and the arrangement direction of the slots is parallel to the axis of the guide roller.

[0012] By adopting the above technical solution, according to the length of the rubber block required for the processing of the seal, the cutting seat is driven to slide along the surface of the machine base, so that the cutting end of the cutter faces the corresponding groove. The roller surface of the pressure roller and the surface of the synchronous belt clamp the two sides of the rubber material in the thickness direction and guide the rubber material to be embedded in the positioning gap. The positioning plate surface and the surface of the machine base correspond one-to-one to clamp the two sides of the rubber material in the thickness direction to form a positioning. The piston rod of the cutting cylinder extends, and the cutting end of the cutter passes through the groove and is embedded in the positioning gap to cut the rubber material to form a rubber block, thereby achieving precise cutting of the rubber block.

[0013] Optionally, the cutting assembly further includes a moving plate and a positioning strip. The machine base has a slide rail on its surface facing the positioning gap for the moving plate to slide. The sliding direction of the moving plate is parallel to the axis of the guide roller. The surface of the moving plate is for placing rubber raw materials. The positioning strip is connected to the surface of the moving plate near the installation station. The surface of the positioning strip facing the positioning gap is for the end face of the rubber raw materials to abut against it to form a positioning.

[0014] By adopting the above technical solution, the moving plate slides along the inner wall of the slideway toward the positioning plate. The surface of the moving plate facing the positioning gap is used to place the rubber material. The roller surface of the pressing roller and the surface of the synchronous belt clamp the two sides of the rubber material in the thickness direction and guide the rubber material to be embedded in the positioning gap. The end face of the rubber material abuts against the surface of the positioning strip facing the positioning gap to form positioning, so that the rubber material is not easy to deviate. When the cutting end of the cutter passes through the groove and embeds into the positioning gap to cut the rubber material to form a rubber block, the moving plate slides along the inner wall of the slideway toward the installation position. The rubber block is separated from the positioning gap, and the limiting effect of the positioning plate on the rubber block disappears. This makes it convenient for the installation device to clamp the rubber block on the moving plate and place it on the molding assembly, further improving the processing efficiency of the seal.

[0015] Optionally, the installation device includes an arrangement assembly and a clamping assembly. The arrangement assembly includes a sliding seat, a transverse seat, an arrangement cylinder, and multiple pneumatic suction cups. The sliding seat is slidably connected to the surface of the machine base facing the installation station, and the sliding direction of the sliding seat is parallel to the axis of the synchronous wheel. The transverse seat is slidably connected to the surface of the sliding seat, and the sliding direction of the transverse seat is parallel to the axis of the guide roller. The arrangement cylinder is connected to the surface of the transverse seat facing the installation station, and the piston rod axis of the arrangement cylinder is parallel to the height direction of the machine base. Multiple pneumatic suction cups are spaced apart and connected to the surface of the arrangement cylinder piston rod facing the installation station. The pneumatic suction cups can adsorb the rubber blocks on the moving plate surface and place them on the surface of the machine base facing the installation station. The arrangement of the multiple rubber blocks corresponds one-to-one with the processing end of the molding component. The clamping assembly is connected to the surface of the machine base and can clamp the multiple rubber blocks on the installation station and embed them one-to-one into the processing end of the molding component.

[0016] By adopting the above technical solution, when the moving plate drives the rubber block to slide along the inner wall of the slide towards the installation station, the transverse seat slides along the surface of the sliding seat towards the moving plate. The suction ends of multiple pneumatic suction cups face the rubber block on the surface of the moving plate. The piston rod of the arranging cylinder extends, and the suction ends of the pneumatic suction cups suction the surface of the rubber block. The piston rod of the arranging cylinder retracts, and the transverse seat slides along the surface of the sliding seat away from the moving plate. The pneumatic suction cups suction the rubber block and face the surface of the machine base located at the installation station. The piston rod of the arranging cylinder extends, and the pneumatic suction cups suction the rubber block and place it on the surface of the machine base facing the installation station. The pneumatic suction cups release the rubber block, and the piston rod of the arranging cylinder retracts. By sliding the sliding seat on the surface of the machine base, the position of the pneumatic suction cups is changed. The above actions are repeated so that the multiple rubber blocks placed on the installation station correspond one-to-one with the processing end on the molding component. The clamping component clamps the multiple rubber blocks on the installation station and places them on the processing end of the molding component, realizing precise and automatic feeding of multiple rubber blocks on the processing end of the molding component.

[0017] Optionally, the clamping assembly includes a clamping seat, a movable seat, a clamping plate, a lifting plate, and multiple ejector pins. The clamping seat is slidably connected to the surface of the machine base, and the sliding direction of the clamping seat is parallel to the height direction of the machine base. The movable seat is slidably connected to the surface of the clamping seat, and the sliding direction of the movable seat is parallel to the axis of the guide roller. The clamping plate is connected to the surface of the movable seat facing the installation station. One end of each ejector pin is spaced apart and connected to the surface of the clamping plate facing the installation station. The other end of each ejector pin can be embedded into the surface of a rubber block on the installation station to form a clamp. The lifting plate is slidably connected to the surface of the clamping plate facing the ejector pins, and the sliding direction of the lifting plate is parallel to the axis of the ejector pins. The lifting plate surface is provided with multiple grooves spaced apart for the ejector pins to slide.

[0018] By adopting the above technical solution, when multiple rubber blocks are placed at intervals on the surface of the machine base facing the installation station, the moving seat slides along the surface of the clamping seat towards the installation station, multiple ejector pins face the multiple rubber blocks at the installation station, the clamping seat slides along the surface of the machine base towards the installation station, the ends of multiple ejector pins are embedded in the surface of multiple rubber blocks at the installation station to form a clamp, the clamping seat slides along the surface of the machine base away from the installation station, multiple ejector pins carry multiple rubber blocks away from the surface of the machine base, the moving seat slides along the surface of the clamping seat towards the molding station, the multiple rubber blocks embedded in the ejector pins correspond one-to-one with the processing ends on the molding assembly, the clamping seat slides along the surface of the machine base towards the molding assembly, the rubber blocks correspond one-to-one with the processing ends on the molding assembly, the lifting plate slides along the ejector pin axis away from the clamping plate, the lifting plate surface abuts against the surface of multiple rubber blocks and pushes the rubber blocks away from the ejector pins, thereby realizing automatic unloading of rubber blocks on the ejector pins and automatic feeding of rubber blocks at the processing ends of the molding assembly.

[0019] Optionally, the molding assembly includes an upper mold, a lower mold, a molding base, and multiple guide pillars. One end of each guide pillar is spaced apart and connected to the surface of the base, while the other end of each guide pillar is spaced apart and connected to the four corners of the upper mold surface. The axes of the guide pillars are parallel to the height direction of the base. The molding base is slidably connected to the surface of the guide pillars, and the sliding direction of the molding base is parallel to the axis of the guide pillars. The lower mold is slidably connected to the surface of the molding base facing the upper mold, and the sliding direction of the lower mold is parallel to the axis of the guide roller. The surface of the lower mold facing the upper mold has multiple cavities spaced apart for accommodating rubber blocks. When the upper and lower molds are closed, the rubber blocks in the cavities can be heated and pressurized to vulcanize and form a sealing component.

[0020] By adopting the above technical solution, when multiple ejector pins are embedded with multiple rubber blocks, the lower mold slides along the surface of the molding base towards the installation position. The multiple rubber blocks embedded in the ejector pins correspond one-to-one with multiple cavities. The clamping seat slides along the surface of the machine base towards the cavity, and the rubber blocks are embedded in the cavity. The lifting plate slides along the ejector pin axis towards the cavity, and the lifting plate surface abuts against the surface of the multiple rubber blocks, causing the multiple rubber blocks to detach from the ejector pins, thus achieving automated feeding of rubber blocks into multiple cavities. The lower mold slides along the surface of the molding base towards the upper mold. The lower mold has a rubber block surface facing the upper mold. The molding seat slides along the guide column axis toward the upper mold. The lower and upper molds close and heat and pressurize the rubber block in the cavity to vulcanize and form a sealing component, realizing automatic molding of the sealing component. At the same time, the rubber blocks in adjacent cavities flow and bond to form a rubber pad. The molding seat slides along the guide column axis toward the direction away from the upper mold. The lower and upper molds open. The lower mold slides along the surface of the molding seat toward the direction away from the upper mold. The lower mold drives the rubber pad to detach from the upper mold, thus facilitating the material feeding component to grab the rubber pad on the surface of the lower mold.

[0021] Optionally, the feeding assembly includes a feeding seat, a feeding cylinder, a feeding plate, and a finger cylinder. The feeding seat is slidably connected to the surface of the machine base, and the sliding direction of the feeding seat is parallel to the axis of the synchronous wheel. The feeding cylinder is connected to the surface of the feeding seat facing the molding station, and the piston rod axis of the feeding cylinder is parallel to the height direction of the machine base. The feeding plate is connected to the surface of the piston rod of the feeding cylinder, and the finger cylinder is connected to the surface of the feeding plate facing the molding station. The finger cylinder is capable of clamping the end of the rubber pad on the surface of the lower mold.

[0022] By adopting the above technical solution, when the lower mold slides away from the upper mold along the surface of the molding base, the lower mold drives the rubber pad to detach from the upper mold, the unloading seat slides towards the lower mold along the surface of the machine base, the gripping end of the finger cylinder faces the end of the rubber pad on the surface of the lower mold, the piston rod of the unloading cylinder extends, the unloading plate drives the finger cylinder to approach the lower mold, the finger cylinder grips the end of the rubber pad on the surface of the lower mold, the piston rod of the unloading cylinder retracts, the finger cylinder grips the end of the rubber pad and drives the rubber pad to detach from the lower mold, the unloading seat slides away from the lower mold along the surface of the machine base, and the finger cylinder drives the rubber pad to approach the unloading station, thus realizing the automated unloading of the rubber pad.

[0023] Optionally, the limiting strip has an adjustment hole for the adjusting rod to pass through. A clamping assembly is connected between the adjusting rod and the limiting strip. The clamping assembly includes a clamping rod and an elastic element. The limiting strip has a clamping hole for the clamping rod to pass through. The axis of the clamping hole and the axis of the adjusting hole are perpendicular to each other, and the clamping hole communicates with the adjusting hole. The adjusting rod has multiple clamping grooves spaced apart for the end of the clamping rod to be embedded in. The arrangement direction of the clamping grooves is parallel to the axis of the adjusting rod. One end of the elastic element in the direction of elastic force is connected to the surface of the clamping rod, and the other end of the elastic element in the direction of elastic force is connected to the surface of the limiting strip. The elastic element has the tendency to force the end of the clamping rod to pass through the clamping hole and be embedded in the clamping groove to form a limiting position.

[0024] By adopting the above technical solution, when it is necessary to adjust the size of the limiting gap, the clamping rod is driven to slide away from the adjusting rod against the elastic force of the elastic element. The end of the clamping rod disengages from the clamping groove, and the limiting effect of the clamping rod on the limiting strip disappears. The limiting strip is then driven to slide along the axis of the adjusting rod to a suitable position. The clamping hole connects with the clamping groove. When the clamping rod is released, the elastic force of the elastic element drives the end of the clamping rod to pass through the clamping hole and embed into the clamping groove. The end face of the clamping rod presses against the inner wall of the clamping groove and limits the sliding of the limiting strip, thereby achieving precise adjustment of the limiting strip in the position of the adjusting rod.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The setup of the feeding assembly, cutting assembly, installation device, molding assembly, and unloading assembly enables automated processing of seal molding, eliminating the need for manual cutting of rubber raw materials into rubber blocks and placing them sequentially on the molding assembly. This reduces the workload for workers, shortens the processing cycle of seals, and thus reduces the processing cost of seals. The setup of guide rollers, mounting rollers, pressure rollers, synchronous pulleys and synchronous belts, with the pressure roller surface and the synchronous belt surface corresponding one-to-one, clamps the two sides of the rubber material and drives the rubber material closer to the cutting station, thus achieving stable transportation of the rubber material; The adjustment rod and the limiting strip are designed so that the surfaces of the two limiting strips correspond one-to-one with the two sides of the rubber material in the width direction to form a limit, so that the rubber material is not easy to deviate on the surface of the synchronous belt, thereby ensuring the accuracy of the cutting component in cutting the rubber material.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a sealing component molding production line. (Refer to...) Figure 1 and Figure 2The sealing component molding production line includes a base 1, a feeding assembly 2, a cutting assembly 3, an installation device 4, a molding assembly 5, and a discharging assembly 6. The base 1 has its bottom abutting against the ground for support. Along its length, the top surface of the base 1 is sequentially equipped with feeding stations, cutting stations, installation stations, and molding stations. The top surface of the base 1 also has a discharging station. The discharging and installation stations are located on both sides of the base 1's width. The feeding assembly 2 is installed on the surface of the base 1 facing the feeding stations. The feeding assembly 2 is used to install and guide the rubber material on the reel towards the cutting stations. The cutting assembly 3 is installed on the surface of the base 1 facing the cutting stations. The cutting assembly 3 can cut the rubber material at the cutting stations into rubber blocks of a specified length. The molding assembly 6 is installed... Mounted on the surface of the machine base 1 facing the molding station, the molding assembly 5 can heat and pressurize multiple rubber blocks to vulcanize and form rubber pads with multiple seals. The mounting device 4 is mounted on the surface of the machine base 1 facing the mounting station. The mounting device 4 can clamp the rubber blocks on the cutting station and place them on the processing end of the molding assembly 5. The unloading assembly 6 is mounted on the surface of the machine base 1 facing the unloading station. The unloading assembly 6 can clamp the rubber pads on the molding assembly 5 and bring them close to the unloading station, realizing automated processing of seal molding. It eliminates the need for workers to manually cut the rubber raw materials into rubber blocks and place them sequentially on the molding assembly 5, reducing the workload of workers, shortening the processing cycle of seals, and thus reducing the processing cost of seals.

[0034] Reference Figure 2 and Figure 3 The feeding assembly 6 includes a guide roller 21, a clearance frame 22, a mounting roller 23, a clamping roller 24, an adjusting rod 25, two limit strips 26, two synchronous pulleys 27, and a synchronous belt 28 used in conjunction with the synchronous pulleys 27. The mounting roller 23 is rotatably connected to the side wall of the machine base 1. The axis of the mounting roller 23 is parallel to the width direction of the machine base 1. The end of the mounting roller 23 is coaxially fitted onto the reel. The clearance frame 22 is fixed to the surface of the machine base 1 by bolts. The inner wall of the clearance frame 22 surrounds the outer circumference of the mounting roller 23. The clearance frame 22 shields the rubber material on the reel, making the rubber material on the reel less susceptible to wear from external impacts, thereby ensuring the quality of the rubber material on the reel.

[0035] Reference Figure 3 and Figure 4 Two synchronous pulleys 27 are rotatably connected to the surface of the machine base 1 at intervals. The axis of the synchronous pulleys 27 is parallel to the width direction of the machine base 1. The synchronous belt 28 tensions and connects the two synchronous pulleys 27. The pressure roller 24 is rotatably connected to the surface of the machine base 1 facing the synchronous belt 28. The axis of the pressure roller 24 is parallel to the width direction of the machine base 1. A pressure gap 241 is left between the roller surface of the pressure roller 24 and the synchronous belt 28 for the rubber material to pass through. The roller surface of the pressure roller 24 and the surface of the synchronous belt 28 correspond one-to-one to clamp the two sides of the rubber material in the thickness direction and drive the rubber material closer to the cutting station.

[0036] Reference Figure 3 and Figure 4 The guide roller 21 is rotatably connected to the surface of the machine base 1. The axis of the guide roller 21 is parallel to the length direction of the machine base 1. The guide roller 21 is located on the side of the pressure roller 24 away from the cutting station. The roller surface of the guide roller 21 is for the rubber raw material to roll into contact and a pressure gap 241 is provided along the surface of the synchronous belt 28. The roller surface of the guide roller 21 rolls into contact with the rubber raw material, reducing the wear on the rubber raw material and thus ensuring the quality of the rubber raw material.

[0037] Reference Figure 3 and Figure 4 The number of adjusting rods 25 can be one, two, or more. In this embodiment, there are two adjusting rods 25, which are connected at intervals on the surface of the machine base 1. The axis of the adjusting rod 25 is parallel to the width direction of the machine base 1. The two adjusting rods 25 are located between the pressure roller 24 and the guide roller 21. Two adjusting holes 261 for the adjusting rods 25 to pass through are opened at one end of the two limiting strips 26 at intervals. The other end of the two limiting strips 26 abuts against the surface of the synchronous belt 28. The limiting strips 26 can slide along the axis of the adjusting rod 25, and a limiting gap 262 for the rubber material to be embedded is left between the two limiting strips 26. The end of the rubber material on the guide roller 21 guides the reel and passes through the limiting gap 262 and the pressure gap 241 in sequence along the surface of the synchronous belt 28. The surfaces of the two limiting strips 26 facing the limiting gap 262 abut against the two sides of the rubber material in the width direction to form a positioning, so that the rubber material is not easy to deviate on the surface of the synchronous belt 28, thereby improving the accuracy of the cutting component 3 in cutting the rubber material.

[0038] Reference Figure 3 and Figure 4 A clamping assembly 7 is installed between the limiting strip 26 and one of the adjusting rods 25. The clamping assembly 7 can limit the sliding of the limiting strip 26 on the adjusting rod 25. The clamping assembly 7 includes a clamping rod 71 and an elastic element 72. The surface of the limiting strip 26 has a clamping hole 263 for the clamping rod 71 to pass through. The axis of the clamping hole 263 is parallel to the height direction of the base 1. The clamping hole 263 is connected to the adjusting hole 261. The surface of the adjusting rod 25 has a plurality of clamping grooves 251 for the end of the clamping rod 71 to be inserted. The arrangement direction of the clamping grooves 251 is parallel to the axis of the adjusting rod 25. The end face of the clamping rod 71 can press against the inner wall of the clamping groove 251 and limit the sliding of the limiting strip 26, thereby ensuring the limiting stability of the limiting strip 26 on the adjusting rod 25.

[0039] Reference Figure 3 and Figure 4The elastic element 72 can be a compression spring or a tension spring. In this embodiment, the elastic element 72 is a compression spring, which has a certain deformation capability. One end of the elastic element 72 in the elastic direction is connected to the surface of the clamping rod 71, and the other end of the elastic element 72 in the elastic direction is connected to the surface of the limiting strip 26. The elastic element 72 has the elastic force to drive the end of the clamping rod 71 through the clamping hole 263 and embed it into the clamping groove 251. The surface of the clamping rod 71 presses against the inner wall of the clamping groove 251 and limits the sliding of the limiting strip 26, so that the limiting gap 262 can be precisely adjusted according to the rubber width, thereby improving the versatility of the production line.

[0040] Reference Figure 4 and Figure 5 The cutting assembly 3 includes a cutting seat 31, a cutting cylinder 32, a moving plate 33, a positioning strip 34, a cutting tool 35, and two positioning plates 36. The two positioning plates 36 are spaced apart on both sides of the machine base 1 in the width direction. A positioning gap 361 is left between the surface of the positioning plates 36 and the surface of the machine base 1 for the rubber material to pass through. The surfaces of the positioning plates 36 and the surface of the machine base 1 correspond one-to-one, clamping the two sides of the rubber material in the thickness direction to form a positioning. The cutting seat 31 is slidably connected to the surface of the machine base 1 near the positioning plates 36. The sliding direction is parallel to the length direction of the base 1. The cutting cylinder 32 is fixed to the surface of the cutting seat 31 facing the positioning plate 36 by bolts. The piston rod axis of the cutting cylinder 32 is parallel to the height direction of the base 1. The cutting tool 35 is connected to the end face of the piston rod of the cutting cylinder 32. The cutting end of the cutting tool 35 faces the plate surface of the positioning plate 36. The plate surface of the positioning plate 36 is provided with multiple slots for the cutting end of the cutting tool 35 to be inserted. The arrangement direction of the slots is parallel to the length direction of the base 1. The slots are connected to the positioning gap 361.

[0052] The implementation principle of a sealing component compression molding production line according to an embodiment of this application is as follows: A reel is installed on a feeding assembly 2, which guides the rubber raw material on the reel to the cutting station. The cutting assembly 3 cuts the rubber raw material on the cutting station into rubber blocks of a specified length. The mounting device 4 clamps the rubber blocks on the cutting station and places them on the processing end of the molding assembly 5. The molding assembly 5 heats and vulcanizes multiple rubber blocks to form rubber pads with multiple sealing components. The unloading assembly 6 is close to the molding station, clamping the rubber pads on the molding assembly 5 and placing them close to the unloading station. This realizes automated processing and molding of sealing components, eliminating the need for workers to manually cut the rubber raw material into rubber blocks and place them sequentially on the molding assembly 5. This reduces the workload of workers, shortens the processing cycle of sealing components, and thus reduces the processing cost of sealing components.
